Abstract

Cette invention concerne un procédé de préparation de compositions de sable consistant à prétraiter des particules de sable manufacturées avec un polycation mitigé avec de l'argile et à les mélanger avec des particules de sable naturelles qui ont été lavées pour éliminer les fines de façon qu'au moins 90 % des particules de sable naturelles soient retenus sur un crible à mailles de 75 microns. Les procédés selon l'invention impliquent également l'utilisation du sable prétraité en mélange pour fabriquer du béton, le sable étant combiné à du ciment, à un dispersant de type polycarboxylate, à une quantité supplémentaire de polycation mitigé avec de l'argile, et à au moins un acide carboxylique hydryoxylé ou hydroxylé ou à un composé de sel.
